摘要：
Japanese Quasi-Zenith Satellite System (QZSS) project has changed to have a positioning/navigation mission only (without the communications and broadcasting mission) since March, 2006. NICT is in charge of the time management system of QZSS. We developed the engineering model of the on-board equipments and are testing them in a space environment and in a launching condition. The ground system, consisting of time management stations and monitor stations, is being designed in detail, and a test antenna was developed. The first Quasi-Zenith Satellite (QZS) will be launched in 2010 and be used for experiments. The schedule of the following satellites is to be decided by the government.
